var strArray = ste.split(',');
console.log("length:" + strArray.length);

(2) 以 中文 或 英文 逗號(hào)分割字符串：字符串既有中文又有英文逗號(hào)

var str = "111,222，333，444,555,666"
var strArray = severalNum.replace(/，/g, ",").split(',');//中文逗號(hào)換成英文逗號(hào)后，再以英文逗號(hào)分割
console.log("length:" + strArray.length);

拓展：使用正則表達(dá)式（未實(shí)現(xiàn)）— 以中英文逗號(hào)分割字符串

var str = "111,222，333，444,555,666"
String regex = ",|，";  //以中英文逗號(hào)分割字符串
//String regex = ",|，|\\s+";  //以中英文逗號(hào)、一個(gè)或多個(gè)空格 分割字符串
String strArray[] = str.split(regex);
for (int i = 0; i < strArray.length; i++) {
      System.out.println(strArray[i]);
